A Columbus' egg idea for CAN media redundancy

Network media redundancy is a clean and effective way of achieving high levels of reliability against temporary medium faults and availability in the presence of permanent faults. This is specially true of critical control applications such as those supported by the Controller Area Network (CAN). In our endeavor to provide CAN with media redundancy we ended-up devising a scheme which is extraordinarily simpler than previous approaches known for CAN or other LANs and field-buses.
